Former Prime Minister Tony Blair, starter of four wars and one national debt crisis, has sought to ease his conscience and improve his reputation as home. He has rushed out his memoirs ahead of his successor as PM, Gordon Brown, and now promises the profits from its sale will go to armed forces charity The British Legion. But such is his history of using a rather flexible interpretation of the truth, more is learned from what he hasn't said than from what he has.Is he donating just the profits, that is, payments less expenses? Is it the royalties without the 4 million pound advance he has already received? Is he paying tax on the donations or is he Gift Aiding it so that much of the charity's gain will be at the expense of taxpayers?And most importantly, will the donation be routed through one of his several companies and so be entirely written off against corporate tax? Blair's donation may cost us more than him, but since at least one of his companies does not file accounts, we may never know if this is a genuine act of altruism.
